There was a report on the BBC about this last week. Apparently their population has exploded in Europe and understandably some farmers are concerned about their livestock. They are requesting permission to start a limited cull in Germany and The Netherlands.
It’s good to see native predators coming back as it will help control pests but I do understand the concern.
Wolves, wild dogs and Canidae in general are very intelligent and will always go for the easy option, if that is your lambs and livelihood you might take the law in to your own hands.
I think allowing the population to establish itself and then target older / larger males and older females might be a way forward in the long term. In the mean time larger / taller fences and use of the big angry sheep dog that was once prevalent in Europe could help limit losses.
